The title and subtitle of the paper purport to summarise the three phases of Stiegler's thought, techno-logical, pharmacological and neganthropological, and at the same time the title intends to exhibit the differential trace of the relationship with Derrida and deconstruction, from which Stiegler develops his ‘politics of memory’. In the first chapter, we will show the Stieglerian attempt to think technique beyond anthropocentrism and instrumentality, which consists in developing an alternative to the philosophical tradition, and which has epiphylogenesis or artificial memory as its main concept and Epimetheus as its conceptual character. In the second chapter we will describe the characteristics of the ‘politics of memory’ elaborated by Stiegler in his second phase, in which he develops a new critique of political economy focused on the pharmacological role of technology. In the third chapter, we will show the meaning of a possible ‘right to technology’, which in Stiegler's perspective would be intrinsically related to a ‘duty of philosophy’ caused by the urgency of the planetary condition. Finally, in the fourth chapter, we will stress the relation between ‘state of fact’ and ‘state of law’, in the third phase of Stiegler’s thought.
